Abstract:

The amide functionality is one of the most important and widely used groups in nature and in medicinal and industrial chemistry. Because of its importance and as the actual synthetic methods suffer from major drawbacks, such as the use of a stoichiometric amount of an activating agent, epimerization and low atom economy, the development of new and efficient amide bond forming reactions is needed. A number of greener and more effective strategies have been studied and developed. The transamidation of primary amides is particularly attractive in terms of atom economy and as ammonia is the single

Abstract:

Background: Amide bond plays a key role in medicinal chemistry, and the analysis of bioactive molecular database revealed that the carboxamide group appears in more than 25% of the existing database drugs. Typically amide bonds are formed from the union of carboxylic acid and amine; however, the product formation does not occur spontaneously. Several synthetic methods have been reported for amide bond formation in literature. Present work demonstrated simple and eco-friendly amide bond formation using carboxylic acid and primary amines through in situ generation of O-acylurea. The reaction was

The most likely association complex between alcohol and DMA is 1:1 stoichiometric complex through the hydroxyl group of the alcohol and the carbonyl group of amide. The results show that the interaction between alcohols and amides is 1:1 complex through the free hydroxyl group of the alcohol and the carbonyl group of amide

Abstract:

A direct and convenient method for the preparation of N-substituted ureas is achieved by treating primary amides with phenyliodine diacetate (PIDA) in the presence of an ammonia source (NH3 or ammonium carbamate) in MeOH. The use of 2,2,2-trifluoroethanol (TFE) as the solvent increases the electrophilicity of the hypervalent iodine species and allows the synthesis of electron-poor carboxamides. This transformation involves a nucleophilic addition of ammonia on the isocyanate intermediate generated in situ by a Hofmann rearrangement of the starting amide.

Primary fatty acid amides (PFAMs) and N-acylglycines (NAGs) are important signaling molecules in the mammalian nervous system, binding to many drug receptors and demonstrating control over sleep, locomotor activity, angiogenesis, vasodilatation, gap junction communication, and many other processes. Oleamide is the best-studied of the PFAMs, while the in vivo activity of the others is largely unstudied. Even less is known about the NAGs, as their discovery as novel compounds is much more recent due to low endogenous levels. Herein is described extraction and quantification techniques for PFAMs

Abstract A narrative approach is taken in this chapter to document and analyze the gendered social and socio-environmental consequences of globalized river basin development using water as the lens to understand the depth and breadth of these changes in people's lives. The chapter is based on primary multi-site ethnographic field research conducted in all three active dam areas of Lesotho in 1997 and 2000-2002, as well as ongoing documentary research. Water remains central within Lesotho's national development plans and to the stability of the region even amid changing climate conditions. More locally, as water becomes more precarious within the lives of highlands residents living near the Lesotho Highlands Water Project (LHWP), this chapter reveals the multi-layered, complex, embodied experiences of infrastructure policy and its consequences, for the everyday lives and livelihoods of people directly affected by these projects.

Abstract:

AbstractBased on evidence and theory, we state that facilitating and supporting people’s meaning-making processes are health promoting. Hence, meaning-in-life is a salutogenic concept.Authors from various disciplines such as nursing, medicine, psychology, philosophy, religion, and arts argue that the human search for meaning is a primary force in life and one of the most fundamental challenges an individual faces. Research demonstrates that meaning is of great importance for mental as well as physical well-being and crucial for health and quality of life. Studies have shown significant correlations between meaning-in-life and physical health measured by lower mortality for all causes of death; meaning is correlated with less cardiovascular disease, less hypertension, better immune function, less depression, and better coping and recovery from illness. Studies have shown that cancer patients who experience a high degree of meaning have a greater ability to tolerate bodily ailments than those who do not find meaning-in-life. Those who, despite pain and fatigue, experience meaning report better quality-of-life than those with low meaning. Hence, if the individual finds meaning despite illness, ailments, and imminent death, well-being, health, and quality-of-life will increase in the current situation. However, when affected by illness and reduced functionality, finding meaning-in-life might prove more difficult. A will to search for meaning is required, as well as health professionals who help patients and their families not only to cope with illness and suffering but also to find meaning amid these experiences. Accordingly, meaning-in-life is considered a vital salutogenic resource and concept.The psychiatrist Viktor Emil Frankl’s theory of “Will to Meaning” forms the basis for modern health science research on meaning; Frankl’s premise was that man has enough to live by, but too little to live for. According to Frankl, logotherapy ventures into the spiritual dimension of human life. The Greek word “logos” means not only meaning but also spirit. However, Frankl highlighted that in a logotherapeutic context, spirituality is not primarily about religiosity—although religiosity can be a part of it—but refers to a specific human dimension that makes us human. Frankl based his theory on three concepts: meaning, freedom to choose and suffering, stating that the latter has no point. People should not look for an inherent meaning in the negative events happening to them, or in their suffering, because the meaning is not there. The meaning is in the attitude people choose while suffering from illness, crises, etc.

Abstract:

Several important hormones such as oxytocin, secretin, and LHRH are known to be peptidyl amides. In addition to these, other peptidyl amides such as indolicidin and the protegrins have been shown to exhibit potent antimicrobial activity. The in vivo production of such compounds is via endogenous enzymatic cleavage of propeptides, making their synthesis by genetic engineering notoriously difficult. Furthermore, to facilitate the survival of synthetic peptidyl amides in vivo, an obvious defence against the action of carboxypeptidases is the N-alkylation of the carboxylic amide terminus. Such secondary amides would be expected to exhibit vastly different solubility and transport properties to primary amides, thus their chemical synthesis is of immense importance. The solid phase synthesis of peptidyl amides and peptidyl N-alkyl amides is centred around two main strategies: 1. Ammonolysis/aminolysis of resin-bound esters. 2. Use of resin-bound primary amines, which may in turn be chemically modified to generate novel secondary amine functionalized linkers for the synthesis of peptidyl N-alkyl amides. Early examples of the use of resin-bound amines for the solid synthesis of peptidyl amides involve the use of linkers such as benzhydrylamine or benzylamine. Following peptide assembly, these linkers require highly acidic (e.g. HF) mediated cleavage, and hence simultaneous removal of acid-labile sidechain protection groups occurs and may cause problems. Systematic modifications of these linker-resins by substitution with electron-donating substituents have resulted in the generation of numerous linker-resins with increased acid sensitivity. Notably, the 4-(2',4'-dimethoxyphenylaminomethyl) phenoxy derivatized (Rink) resin 1, which is cleavable by 95% v/v TFA, and the 5-(2-fluorenylmethoxycarbonylaminornethyl-3,5-dimethoxy)- phenoxyvaleric acid (PAL) linker 2 acidolysed by 75% v/v TFA. Greater acid lability has been achieved using the xanthenyl derivatized resin, 9-(fluorenylmethoxycarbonylamino)xanthen-3-yloxymethyl polystyrene (Sieber amide) resin 3, which besides being cleavable by 1% v/v TFA, holds the added advantage of readily undergoing reductive N-alkylation to afford resin-bound secondary amines for the synthesis of peptidyl N-alkyl amides. In addition to the method detailed below, a number of alternative approaches have recently been reported.

Abstract:

Abstract The paper describes the in-situ polymer sampling in Mangala which helped explain the performance of a large polymer flood in Mangala field in India. The Mangala field contains medium-gravity viscous crude oil. Notably, it is the largest polymer flood in India and 34% of the STOIIP has been produced in 11 years of production. Mangala was put on full field polymer flood in 2015, six years after the start of field production on water flood in 2009. Polymer flood added 93 million barrels above the anticipated water flood recovery in 6 years. Reservoir simulation models could replicate the

Abstract:

The COVID-19 pandemic devastated tourist turnover and caused a crisis of unprecedented proportions in the tourism economy. The strong impact of the pandemic on the tourism sector requires even stronger response of tourism policy, whose primary task is to mitigate the negative effects of the pandemic and, firstly, to propose measures to support the current tourism sector, and then measures aimed at recovering this activity and increasing its flexibility and resistance to future challenges. In this regard, the aim of the paper is to emphasize the importance of effective and responsible tourism p

Abstract:

Abstract Fundamental data has been developed regarding the chemical nature and subsurface transport and fate of wastes generated by amine-based gas sweetening and glycol-based dehydration operations. Results indicate the mobility and biodegradability of both amine- and glycol-based wastes are variable depending primarily on soil type. The data suggest 1) a thorough understanding of site-specific waste and subsurface characteristics is necessary when predicting the fate of gas processing wastes, and 2) glycols may act as cosolvents for less mobile, but more highly regulated, hydrocarbons, there

Abstract:

Carbon dioxide (CO2) capture with amine scrubbing at coal-fired power plants can remove 90% of the CO2 from flue gas, but operational energy requirements reduce net electrical output by 20–30%. Temporarily reducing the load on energy intensive components of the amine scrubbing process could temporarily increase power output and allow additional electricity sales when prices are high. Doing so could entail additional CO2 emissions, or amine solvent storage can be utilized to allow increased power output without additional CO2 emissions. Price-responsive flexible capture is studied for $0–200/tC

Abstract:

The increased use of softer binders in Illinois over the past decade is primarily attributed to the increased use of recycled materials in asphalt pavement construction. The shift in demand of using PG 58-28 over PG 64-22 has resulted in potential alternative methods to produce softer binders more economically using proprietary products. However, there are challenges in using these proprietary products for asphalt modification because of uncertainty in their long-term performance and significant variability in binder chemistry.
